Hi folks!
Just moved into a new hosue; corner house 1923, 114m2, insulated with HR++ glass and an Intergas boiler with panel radiators.
Looking into making the house more confortable and energy efficient and besides likley going to triple glazing + PVC frames, i am also looking into getting a heat pump and maybe solar panels.
Historical gas consumption: 160m3 on feb 2024 to have between 16-18 degrees in the house (and i'd like 20)
I do not have more data since i just moved.
I have a lot of heatboosters in the house and thus i have data.
I am trying to keep 18 degrees in the house, though i'd like to afford to have 20-ish.
What i've observed is that the CV sends 30-35 degrees on warmer days (since the livingroom gets to temp and stays there), and on cold days 40-45. I've rarely see it above and when it's above it's spikes (in the morning).
I've estimated heat loss at around 9kw; around 8 now but i am considering building the 2nd floor, which would add another 40sqm.
Kind of very much confused as to what's worth doing.
1. I can just get thge intergas xtend 5kw for 4k eur; straight forward, no need for heat loss calculation.
2. Other hybrid pumps of higher capacity.
3. Go full electric and gasfree; i understand i need to start from a heat loss calculation to get to the proper pump size as an inccorect size is really impactful; too smal and i freeze, too big and it's premature ware and tear?
3. Get a full electric and keep the CV for DHW/backup; i guess this opens the room to not needing pumps that go to 50 degrees in cold temps.
Due to high cost, floor heating is not an option anytime soon. Which makes me wonder if I need a water buffer tank when going full electric, and if so, how big; i am on radiators though.
Some sellers argue that 50L is enough, others mandate 185L. So i am confused.
Also, amongst the all-electric pumps, i notice a lot of variance on cost; LG is 4k with 3k isde so 1k, panasonic, daikin and mitsu are so much more and i can't get why in specific.
Any guidance is greatly appreciated!
Dank uw well!

Emission system:
- 7 radiators; 1 t33 65x90, t22 90x50, 2x t22 50x200, t11 40x128, t21 50x128, t10 50x128DHW:
- boiler is placed in the shed, no room in the house for it.Heat pump preference:
quiet, economical, home automation integration, DIY/tweaker-friendly, cheap.Who will install it?
